Fix crash when switching monitors
When switching monitors AND displaying notifications at the same time, a rare situation might occur when notification window will be added to two or more stacks. One of the stacks will be removed soon enough, but the "destroy" handler will persist and will be triggered when the window disappears. This results in a reference to a freed memory and (usually) a daemon crash, a typical one is https://retrace.fedoraproject.org/faf/reports/359836/ for example. So, the removal handlers referring to a deleted stack must be cancelled prior to removal. Closes https://github.com/mate-desktop/mate-notification-daemon/pull/34
